The map shows which parts of Saginaw are considered low income and have low access to large grocery stores or supermarkets, or stores that do at least $2 million in sales annually and have sections of the four main food categories including dairy, meat, packaged goods and produce.

The USDA considers a census tract low-income if it has a poverty rate of 20 percent or greater or a median family income at or below 80 percent of the area median family income.

For a rural area to be considered a food desert, it must be low income and 10 miles or farther from a large grocery store. No rural areas in Saginaw County qualify as a food desert under those guidelines, according to the USDA.
